drm/amd/display: Check index msg_id before read or write
[WHAT]
msg_id is used as an array index and it cannot be a negative value, and
therefore cannot be equal to MOD_HDCP_MESSAGE_ID_INVALID (-1).
[HOW]
Check whether msg_id is valid before reading and setting.
This fixes 4 OVERRUN issues reported by Coverity.
